Integrated technology sharing of flue gas desulfurization, dust removal and denitration of StarOne glass kiln
Time:2020-04-27

1. Background information

At present, most glass kilns use heavy oil, natural gas and petroleum coke as fuels. According to the production scale and fuel use, the temperature of the discharged flue gas from the glass kiln is 450 ℃ - 500 ℃, the main pollutants are SO2, dust and NOx, and some heavy metals are contained at the same time. The SO2 emission concentration is 300-3000mg / m3; Compared with burning pulverized coal, glass furnace dust has small particle size, strong adhesion and emission concentration less than 800mg / m3; The emission concentration of NOx is 1800-2870mg / m3. The problem of air pollution emission from glass kilns is serious, so the flue gas of glass kilns must be treated.

2. New process of StarOne

StarOne has developed a new process aiming at the shortcomings of the traditional glass furnace flue gas treatment system, such as long process flow, many system equipment, large operation resistance and high power consumption of fans.

3. Advantages of StarOne's new process

1. The integrated system of high temperature desulfurization + dust and nitrate is adopted, and the ultra-low emission can be achieved without any dust removal equipment at the back end.

2. After the integration of dust and nitrate, the heat is recovered by the waste heat boiler, which has stable operation, high heat exchange efficiency and no pipe blockage.

3. The overall process flow is short, the system resistance is smaller, the cost is lower and the energy consumption is lower.
